Description
Technical field
The utility model relates to a kind of regulator cubicle, is specifically related to a kind of energy-conservation reactive compensation capacitor cabinet.
Background technology
Loadtype major part in electric power system belongs to inductive load, adds that electricity consumption enterprise generally uses power electronic equipment widely, makes power factor of electric network lower.Lower power factor reduces utilization rate of equipment and installations, adds power supply investment, compromises quality of voltage, reduce service life of equipment, considerably increase line loss.In order to improve the factor of energy waste that power factor of electric network lowly brings and these unfavorable power supply productions, power factor of electric network must be made to be effectively improved.If obviously these reactive powers all will provide also Long Distant Transmit to be irrational by generator, are also impossible usually.Reasonable approach is exactly needing the place of reactive power to produce reactive power, namely increasing reactive power compensating apparatus and device.In addition when electric current flows through load, not linear with added voltage, just form non-sinusoidal current, thus generation harmonic wave, use the enterprise of the nonlinear-loads such as great power conversion circuit all can produce serious harmonic wave. high order harmonic component can make the voltage of electrical network and current waveform distort, and the harmonic voltage of same frequency and harmonic current will produce active power and the reactive power of same subharmonic in addition, thus reduction line voltage, increase line loss, waste net capacity.
Utility model content
The utility model is for the deficiencies in the prior art, and provide a kind of safe and reliable energy-conservation reactive compensation capacitor cabinet, it can effectively carry out raising output power factor, reduces reactive power, improves the efficiency of power supply unit, and harmonic inhabitation electric current.
The technical solution of the utility model is achieved in that a kind of energy-conservation reactive compensation capacitor cabinet comprises cabinet, this cabinet is become with lower group by the Over-The-Counter that two are connected by cabinet wall, it is characterized in that: described Over-The-Counter outside is provided with control panel, display module and change over switch; Lower cabinet is from top to bottom connected with fuse, current transformer, filter reactor and Intelligent capacitor in turn.
Described Intelligent capacitor comprises electric capacity, intelligent control module, fling-cut switch module and route protection module; Described intelligent control module is electrically connected with described control panel, fling-cut switch module respectively.
Further, described electric capacity is self-healing low-voltage building-out capacitor, electric capacity built-in temperature sensor.
Further, described fling-cut switch module is made up of thyristor, magnetic latching relay, zero cross fired turning circuit and thyristor protection circuit.
Preferably, described display module is LCD liquid crystal display screen, Dynamic Announce power factor, electric current and reactive power.
The utility model solves the defect existed in background technology, has following beneficial effect:
The energy-conservation reactive compensation capacitor cabinet that the utility model provides, performance safety is reliable.Employing Intelligent capacitor can according to the size automatic switching of reactive load power, and dynamic compensation reactive power, improves the quality of power supply, improves output power factor, reduces reactive power, improves the efficiency of power supply unit; Reduce line loss, reduce the cost of distribution line, saved electric energy.When compensation capacity needs to increase, only need to increase that multiple stage intelligent capacitor is online to be used, greatly increase the compensation capacity of single cabinet, saved cost.In addition obvious effect is played in the suppression of the filter reactor adopted to harmonic wave, effectively improve power factor, the interference from electrical network can be stoped, reduce harmonic current that rectification unit produces to the pollution of electrical network and reduce line loss, save net capacity, achieve energy-saving and cost-reducing object.Create larger economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of energy-conservation reactive compensation capacitor cabinet;
In figure: cabinet under 1-, 2-control panel, 3-display module, 4-change over switch, 5 Over-The-Counters, 6-fuse, 7-current transformer, 9-filter reactor, 10-Intelligent capacitor.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The energy-conservation reactive compensation capacitor cabinet of one as shown in Figure 1 embodiment, comprises cabinet, and the Over-The-Counter 5 that this cabinet is connected by cabinet wall by two and lower cabinet 1 form, and Over-The-Counter 5 outside is provided with control panel 2, display module 3 and change over switch 4; Lower cabinet 1 is from top to bottom connected with fuse 6, current transformer 7, filter reactor 9 and Intelligent capacitor 10 in turn.Intelligent capacitor 10 comprises electric capacity, intelligent control module, fling-cut switch module and route protection module; Intelligent control module is electrically connected with described control panel 2, fling-cut switch module respectively.Electric capacity is self-healing low-voltage building-out capacitor, electric capacity built-in temperature sensor.Fling-cut switch module is made up of thyristor, magnetic latching relay, zero cross fired turning circuit and thyristor protection circuit.Display module 3 is LCD liquid crystal display screen, Dynamic Announce power factor, electric current and reactive power.
The course of work of the present utility model is: Intelligent capacitor 10 forms reactive compensation system, Intelligent capacitor 10 is according to the size automatic switching of reactive load power, dynamic compensation reactive power, improve the quality of power supply, realize capacitor " zero switching ", ensure that switching process no-flashy-flow impacts, without switching overvoltage.Switch module action response speed is fast, can frequent operation.Intelligent capacitor 10 can separate unit use, also can the online use of multiple stage.Multiple stage Intelligent capacitor 10 construction system work automatically, separate unit Intelligent capacitor fault then logs off automatically, and do not affect other Intelligent capacitor work, reliability is high.In Intelligent capacitor 10 loop, filter reactor 9 (i.e. series filtering reactor) is installed, plays a part when Intelligent capacitor 10 loop is dropped into suppress to shove.Form harmonic wave loop together with Intelligent capacitor 10 simultaneously, play the filter action of each harmonic, enough effectively suppress surge, harmonic inhabitation electric current, effectively improve power factor, the interference from electrical network can be stoped, reduce the harmonic current of rectification unit generation to the pollution of electrical network.
